DEAD-PLATE FOR BOILERS.

To all whom it may concern:

Be it known that I, JOHN W. CHAMBERS, a citizen of the United States,residing at Newark, in the county of Newcastle and State of Delaware,have invented a new and useful Improvement in Dead-Plates for Boilers,of which the following is a specification.

This invention relates to certain new and useful improvements in deadplates for boilers, the object being to provide a dead plate which iscast in one piece in such a manner that the water will have a freecirculation' through the same so as to lengthen the life and prevent thedead plate from burning out.

Another object of the invention is to provide a dead plate which isprovided with inwardly projecting partitions so arranged with respect tothe inlet and outlet that the water through the dead plate will travelin a zigzag manner to keep the dead plate cooled at all times. 7

A still further object of the invention is to provide a dead plate whichis exceedingly simple and cheap in construction and one in which theinlet is arranged at one end and the outlet at the other in order tocause the water to travel longitudinally through the dead plate.

With these various objects in view my invention consists in the novelfeatures of construction, combination and arrangement of partshereinafter "fully described and pointed out in the claim.

In the drawing forming a part of this specification: Figure 1 is a frontelevation of my improved dead plate. Fig. 2 is a vertical sectionthrough the plate. Fig. 3 is a horizontal section through the same.

In carrying out my improved invention, I employ an oblong casting whichis preferably Specification of Letters Patent.

Application filed July 14, 1910.

Patented May '7, 1912.

Serial No. 571,987.

said partitions are a plurality of inwardly projecting partitions C,which extend inwardly from the opposite sides of the casting in such amanner that the water entering one end will pass around the ends of therespective partitions as clearly shown in order to cool the same. Thecasting is provided with an inlet pipe D at one end and an outlet E atthe other end through which water is adapted to pass and can beconnected to any suitable supply desired so as to cause a completecirculation of the water. By having the partitions arranged in thismanner and the feed and outlet pipes arranged at the ends, the watersupply can be readily connected or disconnected and the device can bereadily removed or placed in position.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent, is

A dead plate for boilers comprising a rectangular oblong casing, solidtransverse partitions arranged adjacent the ends of said casing, and aplurality of intermediate partitions arranged between the partitionsfirst mentioned, said intermediate partitions stopping short of a sidewall of the casing, and being arranged oppositely with respect to eachother, and means for admitting water and withdrawing water from thespace between the said first mentioned partitions.
